Answer:</h3>
4.73 × 10^4 m
<h3>
Explanation:</h3>
From the question;
Frequency of the photon = 634 × 10^12 Hz
We are required to calculate the wavelength of the photon.
We need to know the relationship between wavelength and frequency of a wave.
The relationship between f and λ is given by;
c = fλ
Where c, is the speed of light, 2.998 × 10^8 m/s
Therefore, to get the wavelength we rearrange the formula such that;
λ = c ÷ f
= 2.998 × 10^8 m/s ÷ 634 × 10^12 Hz
= 4.73 × 10^-5 m
But we require wavelength in nm
1 M = 10^9 nm
Therefore;
Wavelength = 4.73 × 10^-5 m × 10^9 nm/m
= 4.73 × 10^4 m
Hence, the photon's wavelength is 4.73 × 10^4 m
Actual yield/theoretical yield x 100
Solvent is the coffee beans/coffee powder
Solute is hot water
The core of the atom contains a nucleus. That nucleus is made up of protons and neutrons.
Protons are made up two up quarks and a down quark. Up quarks have a charge of +2/3 and down quarks have a charge of -1/3.
+2/3 + 2/3 -1/3 = +4/3 - 1/3 = +3/3 = +1. This means that protons have a positive charge.
Neutrons are made up of two down quarks and an up quark.
-1/3 - 1/3 + 2/3 = -2/3 + 2/3 = 0. This means that neutrons have no charge, or a neutral charge.
The two ways to make a saturated solution are 1 reducing the temperature of the solution and Adding more solute.<span> </span>
